1 INTRODUCTION
The Centra-GP8 series are general purpose centrifuges designed for use
in medical, industrial and scientific laboratories. The Centra-GP8 series is
available in the following models.
Benchtop models: 3121 - GP8 100/120/220/240 Vac, 50/60 Hz
3122 - GP8R 120 Vac, 60 Hz
3125 - GP8R 200/220/240 Vac, 50/60 Hz
Kneewell models: 3123 - GP8(K) 100/120/220/240 Vac, 50/60 Hz
3124 - GP8R(K)120 Vac, 60 Hz
3126 - GP8R(K) 200/220/240 Vac, 50/60 Hz
Floor Models: 3127 - GP8(F) 100/120/220/240 Vac, 50/60 Hz
3128 - GP8R(F)120 Vac, 60 Hz
3129 - GP8R(F)220/240 Vac, 50/60 Hz
The Centra-GP8 series can develop a maximum relative centrifugal force
(RCF) of 4630 xg using the 822A rotor. The centrifuges will accommodate
a range of centrifuge tubes and devices including 750 mL bottles,
microplates, cytological slide carriers, and microsample tubes. Maximum
sample load is 3 Liters.
Designed for ease of use, the Centra-GP8 has an ergonomic touch pad
control panel and bright, easily read LED displays. The unit can be
operated in manual mode, hold, or one of 35 programmable operations.
Programs can also be modified at run time, offering unlimited run
variations. In addition, rotor number entry permits automatic calculation of
RCF. Other features include a coast mode and separate acceleration and
deceleration controls for maintaining delicate samples such as those with
density gradients.
All refrigerated models allow you to select chamber temperatures from
-5°C to 40°C and will maintain 2°C at full speed with the 218 rotor. All
refrigerated models also offer a Rapid Condition function for pre-cooling
or pre-heating the rotor and sample chamber. Repeat runs with precisely
the same temperature, speed and time setting can be achieved with the
touch of a button.
The internal microprocessor that allows this simplified operation also
ensures repeatable results, preventing inadvertent loss of sample, and
even alerts operators when periodic maintenance is due.
The Centra-GP8 series rugged steel cabinet and rigid construction
provide quiet operation and long-term reliability coupled with impressive
safety features. A fail-safe cover interlock prevents the rotor from running
unless the cover is closed. It also prevents the cover from being opened
until the rotor has slowed to less than 90 RPM, even if the power fails. If a
load-imbalance occurs, a sensor shuts the unit down and triggers a
warning message.
